The charger terminates at a 4.2V battery pack voltage, the standard for Li-Ion cells, and includes over-voltage fault protection to keep the cell from seeing a runaway charge condition. The constant-current charge level is programmable via an external resistor, and a timer provides a backup termination if the current taper doesn't trigger first. ## Package and board-fit for hand-soldering It comes in a 28-WFQFN with an exposed pad (4x4 mm, 28-TQFN supplier package designation). That exposed pad is the main thermal path — you'll want a solid via array under it to the ground plane to keep the die temperature in check at 2A charge current. Surface-mount only, so plan for a reflow profile or a hot-air station.","metaTitle":"MAX8903AETI+T Analog Devices Battery Charger IC, 2A, 28-TQFN","metaDescription":"MAX8903AETI+T Analog Devices Li-Ion battery charger IC, 2A max charge current, USB interface, 16V supply max, 28-TQFN.
